And now that at least one manufacturer has taken advantage of electronic technology and offers motive power that can run on either type of rail and almost any power source, a turnout that will permit both two rail and also three rail motive power and rolling stock is the one "missing link" that would permit complete and non compromised interoperability.....
So the question is: "Is it easier to offer modified wheels and flanges, or should turnout issues be resolved to permit this interoperability?"
